Does Maywood, California have zoning, and what does it mean for RVs, tiny homes and setbacks?

Yes. Maywood has its own zoning ordinance, and the city code refers to parcels "zoned for residential use according to the Maywood Zoning Ordinance"². The City of Maywood Planning Division administers it and handles zoning questions, zoning verification letters, conditional use permits, variances, fence permits and home occupation approvals⁷.

The Los Angeles County zoning code applies only to unincorporated land, not automatically to cities⁸. So county figures you may find online, such as the county's minimum home size or setbacks, do not set the rules for a lot inside Maywood⁹.

We could not confirm Maywood's district-by-district rules for lot size, setbacks, height, RV living, tiny homes or accessory dwelling units. Call the Planning Division at (323) 562-5723 and ask for the zoning district of your parcel before you buy or plan anything⁷.

Do you need a building permit in Maywood, and who issues it?

Yes. The City of Maywood Building Division issues building permits and performs site inspections inside city limits¹. The city states that permits are required for all new construction and in most cases for building modifications, replacements and remodeling¹.

Maywood has adopted the 2025 California Residential Code by reference, with local amendments⁴. Residential work inside the city is built to that code, not to a county-written version.

Los Angeles County Public Works issues building permits only for unincorporated properties, and another office handles properties outside its jurisdiction¹⁰. A Maywood address belongs to the city's Building Division, not the county counter.

Building inspections are conducted on Tuesdays and Thursdays¹.

How do septic permits work inside Maywood?

Septic is the exception to what the city decides. Maywood's code makes it unlawful to construct or maintain a privy, septic tank, cesspool or seepage pit unless the chapter provides otherwise⁵. Where a private system is permitted, its type, capacity, location and layout must follow the recommendations of the Los Angeles County Department of Public Health and state law³.

The city will not issue a permit for a subsurface absorption system on a lot under 10,000 square feet¹¹. Once public sewer becomes available, existing septic tanks and cesspools must be abandoned and the property must connect directly to the sewer⁶.

For most Maywood lots, the practical answer is sewer service. If you think a lot might qualify for a septic system, ask the Los Angeles County Department of Public Health's Onsite Wastewater Treatment Program¹² and the city's Building Division¹ before you make an offer.

Building a home in Maywood: the steps, in order

1. Call the Planning Division at (323) 562-5723 to confirm your parcel's zoning district and what the zoning ordinance allows⁷.
2. Confirm sewer service. Septic is generally unlawful in the city, so a connection to the public sewer is the expected route⁵⁶.
3. Design to the 2025 California Residential Code as Maywood amends it⁴.
4. Book a plan check appointment with the Building Division and apply for your building permit¹.
5. Schedule inspections as work proceeds; the city conducts them on Tuesdays and Thursdays¹.
6. Finish with the occupancy approval the city requires for new businesses; ask the Building Division what applies to a residence¹.

What stays with Los Angeles County, and what to check before you buy in Maywood?

Septic review is the main piece that involves the county: Maywood's code defers to Los Angeles County Department of Public Health recommendations³. We could not confirm Maywood's rules on private wells, so ask the Building Division before assuming a well is possible¹.

If your land lies outside Maywood's city limits, the county's rules apply instead; see the Los Angeles County page for unincorporated land.

Before you buy, ask the city three things: the parcel's zoning district, whether the parcel is on public sewer, and the permit history for any existing structures⁷¹. We could not confirm Maywood's fee schedule or its accessory dwelling unit rules, so ask for those in writing.

Watch-outs

• Los Angeles County's rules for RVs, tiny homes, minimum home size and setbacks apply to unincorporated land only; we could not confirm Maywood's own rules, so ask the Planning Division at (323) 562-5723⁷.
• Septic is generally unlawful inside Maywood, and no subsurface absorption permit is issued on a lot under 10,000 square feet⁵¹¹.
• Maywood adopted its 2025 California Residential Code ordinance with local amendments, so ask the Building Division which amendments apply to your project⁴.
